Application filed December 7, 1925,. Serial no. 73,5'43, and in FranceDecember a,

The object of my invention is a machine which allows part of themanufacture of shoes with Louis heels to be made with much lesshandicraftthan has been used up This machine is used before the-...,heels are fixed on the rear "part of the* soles. I will first statehow the sole of a shoe with Louis-heels is made. 1) comprises atits rearpart-two tongues, the former of which passes inthe finished shoe betweenthe heel and the shoe, the other be- I the tongue 2 which strip 3',

hollowed out portion of *of the machine,

ing folded over and stuck to thefront of. the heel so as to reinforcethe means for'securing the heel to theshoe. Up till now all thesetongues have been prepared by hand: the rear part of the sole havingbeen cleft previously, cured. to the lower part of the shoe and thetongues 2 and 3 are then cut.

The machine according to'my invention will cut these partsautomatically.

Before describing the principal features I willbegin' by showing theoperations it has to carry out. These operations are showndiagrammatically on Figs. 2 2 2 -and 3.. 3,, 3 the Figs 2 and 3 beingside views, the Figs. 2 and 3 plan views and Figs. 2 and 3 detail viewson an enlarged sea e.

The first stage (Fig. 2) consists in cutting is to be placed between theheel and the shoe; this operation consisting in bringing the shoe-4under a press-knife 5. The. two strips 2' and 3 are shownbeforelcutting. The strip 2' is folded over the bearing plate 6, thestrip 3 being held forward. The tongue 2 which is obtained by thiscutting operation will have the shape of the hollowed out portion 7 ofthe press-knife 5. In view of the second-stage of the operation (Fig..2) which consists in cutting the tongue 3 out of the a secondpress-knife 8 is usedthe shape of the front part of the heel and is muchlarger'than the hollowed out portion 7 But if the press- 7 of thepress-lmife-.5.

I knife were to cut the strip ,3 whilst the tongue 2 is still resting onthe plate 6, the

cuttingv would not be properly done as the strip 3 would not lie quiteflat. Therefore the plate 6 is replaced by a hollowed out auxiliaryplate'lO provided with a supporting plate 6', the shape of the hollowedout portion-of the plate IO-being exactly the shoe for cutting'the Thissole 1 (Fig;

:secured to-the frame so the front of the sole is first'se-.

with its sole 1 which has the exact.

other hand is seated, this being provided "by the exactcorrespondencybetweenthe'tongue 2 andthe hollowed i out portion of. jthe auxiliary plate 10.

y The machine for carrying out these open. 55

fit-IOIIS comprises a frame wherein the pressknife is adaptedto -move toand ,fro. A 1110 able vise supporting the shoe allows it to e broughtunder "the press-knife and allows it to be moved vertically with ref-ference thereto." Finally, ,a. -bearing' '-plate is as to] support theleather which is being cut. r

In order to carry out the first stage of the operations the machineshould comprise a device allowing the position of theshoe with referenceto the press-knife'to be ad justed accurately, this adjustment varyingwith the size of the shoes. This device is constituted preferably by astop which'has the exact shape of: the rear part of the shoe and isadapted to be moved by a screw'which has only a longitudinal motionproducedby a vernier cooperating with a scale'pro- For the secondoperation the machine is provided with an auxiliary plate thehollowedout'portion of which is the same as that of the press-knifewhich has served for the first operation; this plate can be secured "toa supporting-plate andholds-thetongue cut during the first operationwhilst the second is being formed.

Evidently -if the number of shoes to work upon is great enough, it beofadvantage to .use two different machines for carry- 'lngout thetwooperati'ons; the use of two machines does not widen to a y gree theScope f he invention. 1

A machine according'to myinventionis describedhereinbelow byway ofvexample and shown on appended drawings wherein; Figs. 1, 2 2 ,-2 3.,353., are the explanatorv diagrams described already. I

Figs. 4 and 5'a1-e'\two vertical views per- Fig. 6 is a detail of Fig. 4at an enlarged scale, Figure 4 showing themachine'ready for tle firstoperation and Figure 6for the secon pendicularone-with referenc'e'totheoth'er;, i

In the frame 12 ashaft 13 is adapted to rotate. It bears the controllever 14 and the eccentric parts 15 which actuate through the small red16 a piston 17 which bears t e ress knife'5 or 8 shown on Figs. 2 and 3.

he piston 17 is uided in the sleeve 18. Its deflectiontowards the rightor the left is prevented by a stud (not shown) sliding in a grooveprovided in the frame 12.

The frame shows a slide 19 wherein the sole 20 of the vise whichsupports the shoe is adapted to move. To this'sole is secured a threadedscrew 21 cooperating witli the threaded sleeve 22 which allows the suport 23 of the shoe to be raised or lowered. This support is inde endentof the sleeve and simply rests on it so as not to rotate along with it.The movement of the sole is stopped by a stop plate 24. It can besecured in its correct position b means of a lever 25, the eccentricpivot 0 which bears against a blocking part .28. 5

The accuracy of theposition of the shoe for the first operation isensured by the stop 29 which is hollowed out so as to show the exactshape of the seat or rear art of the shoe. This stop is securedto t eend of a threaded rod 30 which passes through a controlling nut 31 heldby the frame so as to be unable to move longitudinally along the rod 30.The latter on the other hand, is provided with a rear part 32 having asquare section adapted to move in a square hole, whereby the threadedrod 30 is prevented from rotating. By actuating the nut 31 the stop 29is caused to move forward or rearward. A vernier late 33 is secured tothe rod 30 and moves in front of the stationary scale 34'disposed on theframe, thereby enabling a correct placing of the stop according to thesize of the shoe. For the second 'operation the-auxiliary plate 10 gFig.6) is secured on a sup orting s stated hereinbefore this ollowe outplate allows the accurate placing of the shoe with reference to thepress-knife.

late.-

eeann The form of execution which has been described has only been givenby way of example and any constructional modifications can be brought toit without extending the scope of the invention. Thus for instance theplate 6 could instead of being secured to the frame-of the machine besecured to the press-knife holder with the interposition of springs. I

Evidently if as already stated, two machines are used, theone intendedfor the second operation need not be provided with an adjustable stop 29because in this case the shoe can be accurately put in place by means ofthe tongue punched during th first operation.

What I claim is:

1. In a heel seat fitting machine, a frame, a shoe supportcarried-thereby, a press knife mounted in the frame for movement towardsand from a shoe on said su port, a bearing plate carried by the frame orsup orting a flap onthe rear portion of the so e of the supported shoewhich has been previously cut in such a manner as to adapt it to beinserted between the shoe and a heel to be attached thereto, and asecond plate secured to the bearing plate for supporting a second flapon the rear portion of said sole and having a hollowed out portion theside edges of which correspond to the sideedges of the first mentionedreviously cut flap.

2. Ina machine as c aimed in claim 1, the combination of'a stop adaptedto fit against the seat of the shoe, a screw secured to said stop, a nutcooperating with the screw and ada ted to move it longitudinallytogether witi the stop, means whereby the screw is prevented fromrotating, means whereby the nut is prevented from moving longitudinally,a vernier borne by the screw, and a graduation borne by the frame infront of said "ernier.

In testimony whereof I have aiiixed my signature. 1
